Functioning

The sanitary grates can only be removed during maintenance, for example during cutting.

When you are present, you supply the filters with water and organic matter, so the channel retains a water supply even if the evapotranspiration is greater and the vegetation more demanding.

If, however, you are absent during a period of drought, the vegetation may suffer a little and the reeds may turn yellow, for example, but the recommended plants are very hardy and recover quickly.

In the event of prolonged absence during a heatwave, watering can be set up (like the plants in your garden) to avoid causing the plants prolonged water stress.

After treatment, the water returns to the natural environment (infiltration into the soil, ditch, etc.) or can be used for underground irrigation in the ornamental garden

Planted filters, like any sanitation system, are effective in treating natural organic matter. Chemical products are minimally processed and therefore end up in nature.

You don’t need to change your habits to protect your phyto-purification because it is very robust, but you can do so for nature!

The filters are sized to receive domestic wastewater; green waste must be composted in a bin dedicated for this purpose.

The water seeps into the gravel beds quickly enough for pests to get away.

In winter, the water supply throughout the day limits frost. In addition, if there is frost, it is only on the surface of the planted filters: bacterial life continues beneath the surface and, let us remember, it is the microorganisms that do the work. The same thing can be observed in conventional underground channels, such as spreading and sand filters: the topsoil that covers the installation may be frozen, but the microorganisms are still below. There is thus no more disadvantage with the plant channel. Finally, it should be noted that the aquatic plants installed are plants that are found naturally in bodies of water and are very resistant to frost.

However, it is true that microbial populations react in different ways depending on the temperature. To protect the surface of the planted filter, we recommend that you only cut dry plant parts at the end of winter (end of February, beginning of March) to leave a plant cover.

The was tested in all conditions during its approval and the results obtained in the absence of wastewater are excellent.

The bacteria present in the filters do not ferment, they breathe! There is therefore no odour when the system is working correctly.

Because it is a living system which is able to adapt to the polluting load quickly.

Phyto-purification is an innovative system with no tank or emptying, offering both an environmental and beautiful solution. Its main advantages are:

• • Performance
    • Approved by the Ministries of Health and the Environment
    • Adapts to the volume of water to be treated
    • Works in any season and on any terrain
  • Economical
    • Low dedicated space
    • Competitive investment over time
    • Low maintenance costs
  • Beautiful
    • Optimised landscape integration
    • Oasis of plants and flowers
    • Flowers from May to August
  • Sustainable
    • Sanitised water returned to the natural environment
    • Zero waste output
    • Reliable; lifespan of at least 40 years

The word phyto-purification combines two words:

Purification, purifying and sanitising wastewater, and phyto, which means “plants”. It is therefore a natural process: it is thanks to plants that we purify the wastewater. Nevertheless, it is not the plants themselves that act, but the bacteria that live in the immediate environment of semi-aquatic plants.
